BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket, throttle body gasket, and a new intake boot to make your separator change easier and more comprehensive.

It's no secret that the B58 BMW turbo motors can suffer from oil control problems causing the oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels the more apparent these problems become. The solution to this problem has finally arrived. The BMS oil catch can. While there are other catch cans on the market they all fall short in various areas. Some are mounted on the hot/turbo side of the motor preventing proper vapor condensation. Others utilize hoses that are too small and runs that are too long to allow proper PCV ventilation causing internal motor/ring sealing issues. Some have insufficient or no internal baffle system while others have internal baffles systems that are too restrictive. Some even bypass the PCV system all together venting crankcase gas and odor to the atmosphere. Most are simply repackaged oil catch cans from smaller/lower power motors shoehorned into place in the turbo BMW engine bay. To solve these problems Burger Motorsports designed their oil catch can kit from the ground up specifically for the B58 turbo BMW application. It features 100% CNC machining with zero welding for a precision fit and long life. The can itself is guaranteed for the life of the vehicle. The hoses exceed the OEM PCV piping in diameter and that flow rate is maintained throughout the entire oil catch can ensuring no excessive crankcase pressure buildup. The BMS OCC retains the factory fully closed loop PCV operation preventing any PCV vapor from leaking to atmosphere. The mounting locations are selected to minimize the line length, allow more efficient operation, and retain a stealth look. Install takes around 20 minutes, includes all required hardware, and is 100% reversible. Simply unscrew the base of the can or use the drain plug to safely dispose of captured oil with the rest of your used motor oil during oil changes. Made in the USA. KIT INCLUDES (1) BMS N54 Oil Catch Can (1) Billet B58 bracket (1) 90º billet fitting/nipple (1) Custom Silicone inlet hose (1) 3.5" Straight hose (2) Stainless steel bracket screws #10-32 x 1/2" internal hex socket head Includes BMS intake silencer delete for installation with factory intake.

The engine crankcase breather hose is a vital part of the Positive Crankcase Ventilation (PCV) system, responsible for directing pressurized air from the engine crankcase to the air/oil separator, also known as the PCV valve. This separator removes oil vapors from the air, allowing the oil to return to the engine while feeding the filtered air back into the intake system to support efficient combustion.

As a byproduct of the combustion process, positive crankcase pressure naturally builds up in the engine. The breather hose operates under constant exposure to heat, pressure, and an air/oil vapor mixture, making it prone to wear and failure over time. Ensuring the breather hose is in proper working condition is crucial for maintaining engine performance, adhering to emissions standards, and preserving the functionality of the PCV system. Promptly replace this component at the first signs of damage or degradation to avoid further complications.

By diverting oil-laden vapors into a catch can instead of back through the intake, this system helps minimize carbon buildup, reduces oily contamination, and promotes more consistent performance as power levels climb. High-quality hoses and fittings ensure a secure, leak-free install that won’t collapse under pressure and maintains a clean, OE-plus appearance in the engine bay. An easy, effective upgrade for B58 enthusiasts looking for cleaner operation, improved engine longevity, and proven performance-focused design

It's no secret that B58 BMW turbo motors can suffer from oil control problems, causing the oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels and the higher the mileage, the more apparent these problems become. The solution to this problem has finally arrived. The Burger Motorsports oil catch can. While there are other catch cans on the market, they all fall short in various areas. Some are mounted on the hot/turbo side of the motor, preventing proper vapor condensation. Others utilize hoses that are too small and runs that are too long to allow proper PCV ventilation, causing internal motor/ring sealing issues. Some have insufficient or no internal baffle systems, while others have internal baffle systems that are too restrictive. Some even bypass the PCV system altogether, venting crankcase gas and odor to the atmosphere. Most are simply repackaged oil catch cans from smaller/lower power motors shoehorned into place in the turbo BMW engine bay. To solve these problems, Burger Motorsports designed their oil catch can kit from the ground up specifically for the 2025 and newer Gen 3 B58 turbo BMW application. It features 100% CNC machining with zero welding for a precision fit and long life. The can itself is guaranteed for the life of the vehicle. The hoses exceed the OEM PCV piping in diameter, and that flow rate is maintained throughout the entire oil catch can, ensuring no excessive crankcase pressure buildup. The BMS OCC retains the factory fully closed loop PCV operation, preventing any PCV vapor from leaking to the atmosphere. The mounting locations are selected to minimize the line length, allow more efficient operation, and retain a stealth look. Installation takes around 20 minutes, includes all required hardware, and is 100% reversible. Simply unscrew the base of the can or use the drain plug to safely dispose of captured oil with the rest of your used motor oil during oil changes.
